24 Claims.

My'invention relates to improvements in looms for weaving cloth andprobably for other purposes.

Briefly stated, the invention has for its lprimary object to providemeans which is readily applicableto standard types of non-automaticlooms, without substantial'modication of the working Vparts thereof, forconverting same into automatic `looms whose working shuttles, the quillsof which may carry different varieties of thread, are -selectively vandautomatically changed when their `thread is substantially exhausted, thenature of the invention being such that such shuttle changes can :beeffected without necessitating stopping of the loom.

`The invention also contemplates the provision in ran automatic loom (orin attachment means lfor converting a non-automatic loom into anautomatic loom) of (l) A novel magazine for receiving replacement`shuttles having different varieties of thread, `and .which magazineembodies novel means operated by a detector-controlled timing means, orthe equivalent, for disposing a particular shuttle in position -to beejected; the magazine vfurther having novel lay-operated means forejectingY the selected shuttle into the shuttle box of the loom; v

(2) A shuttle box which in normal running of the loom is controlled bythe head motion, or the like, in the usual manner, but which has a novel-shuttle-ejecting means in one cell, which latter is automaticallybrought to alignment with the raceway of 'the lay to receive anexhausted shuttle; said cell having means for eiecting stopping oftheloom in the event that the exhausted shuttle is not received fordischarge;

v(3) A novel empty shuttle receiving container having closure meansvenabling shuttles to be safely extracted therefrom while the loom is inoperation and shuttle changes are being made;

(4) A novel magazine and shuttle box control yunit arranged to be set inoperation 'by the feeler motion (or other means/ capable of detecting asubstantially empty quill in a shuttle) and which controlunit preferablyacts through the normal shuttle box shifting means, and in conjunctionwith the head motion, or other control thereof, vnot only for disposingthe shuttle box in position to eject a spent shuttle and receive a newone having the same variety of thread as the ejected one, but also insuch subsequenty shifts of the shuttle box as are necessary to effectoperation of the replacement shuttle from the proper cell Vof thevshuttle box; and

to its shuttle-receiving and ejecting position, after the proper shuttleof the magazine has been disposed in position to be ejectedtherefrom.

Other objects and advantages of the invention reside in certain novelfeatures of construction,

combination and arrangement of the various 4l0 parts, and in modes ofoperation thereof,-all of which will be readily apparent to thoseskilled in -the art from a reading of the following detailed descriptionof the now preferred example of the invention, which is illustrated inthe accompanying drawings forming a part of this specication.

It is to be understood, however, that specific disclosures herein are tobe taken merely as illustrative, and that the invention is susceptibleof other mechanical expressions within the spirit and scope of theVappended claims.

In the drawings, wherein the same reference characters have been used todesignate the same parts in all views,

Figure '5 is a perspective view of the novel magazine detached, certainportions being broken away and sectioned to illustrate the verticallyslidable and relatively shiftable shuttle-carrying sections, and also toillustrate the downwardly acting shuttle ejecting plunger;v

Figure 6 is .a Aperspective viewof a novel shuttle actuating slidemember, which is incorporated in the magazine of Figures 1, 2, 3 and 5;

Figure '7 is a detailed perspective of a swingable shuttle support whichis incorporated in the magazine;

Figure is a sectional view taken on the line 8 8 of Figure 2,butillustrating the shuttle box at the uppermost limit of its travel, sothat its lower cell is aligned with the raceway of the lay to receive anexhausted shuttle; the view also illustrating the lay-carried daggeractuating the shuttle-ejecting means of the magazine;

Figure 9 is a cross-sectional View taken approximately on the plane ofline 9-9 of Figure 2, but illustrating the shuttle-carrying magazineAsections of the magazine shifted to a different position from that shownin Figures 1, 2, 3, and and also showing the shuttle actuating slide inthe position that it assumesV after having actuated a shuttle into theswinging supports (Fig. 7 below the downwardly acting ejecting plungerthatis disposed above the open top cell of the shuttle box, which isillustrated fragmentarily in cross-section; Y
